Verifying STK Results Scenario 1 – A vertical burn was used to slow the penetrator down to 0 m/s at the desired altitude of about 28.1 km – Amount of fuel required is about 11.2 kg Scenario 2 – A vertical burn was used to slow the penetrator down to 300 m/s at the surface of the moon – Amount of fuel required is about 9.7 kg 2008-11-21 10Tommy Yuen

Conclusion Geometric link time is about 80 to 7000 s Hohmann transfer is not a plausible option STK results agree with back of the envelope calculations 2008-11-21 11Tommy Yuen
